Anti-concentration of polynomials: balls and symmetric measures
Itay Glazer, Dan Mikulincer
We begin with the observation, based on previous results, that dimension-free lower bounds on the variance of a polynomial under a log-concave measure yield dimension-free small-ba…

Fast mixing in Ising models with a negative spectral outlier via Gaussian approximation
Dan Mikulincer, Youngtak Sohn
We study the mixing time of Glauber dynamics for Ising models in which the interaction matrix contains a single negative spectral outlier. This class includes the anti-ferromagneti…
